4. OPERATIONNOTE: All models display an 8 in all digits for 1 sec. at power-up.

700 Hour Meter (AC/DC)To Display & Operate: Apply DC+ or AC hot to pin 1 and DC – or AC neutral to pin 2. The accumulation of elapsed time is indicated by the flashing hourglass icon. If power has been applied for 5 seconds minimum, the accumulated time will be stored in non-volatile memory when power is removed.

To Reset: (for Resettable Models) Apply DC+ or AC hot to pin 4 for 1/2 second minimum while power (pins 1 & 2) is applied for 5 seconds minimum. The reset voltage must be at the same level as the voltage used to power the unit.

701 Hour Meter (AC/DC or DC Only)To Display: Apply DC+ or AC hot to pin 1 and DC– or AC neutral to pin 2. The display is activated at this point but the elapsed time will not be accumulated until a signal is applied to pin 3. Note, for proper operation: Power must be applied to pins 1 & 2 before or coincident with pin 3.

16

701 Hour Meter continuedTo Operate: Apply DC+ or AC hot to pin 3 for 1/2 second minimum (AC/DC model) or DC+ for 1 millisecond mimimum (DC Only model). The accumulation of elapsed time is indicated by the flashing hourglass icon. If power (pins 1 & 2) has been applied for 5 seconds minimum, the accumulated time will be stored in non-volatile memory when power is removed.

To Reset: (for Resettable Models) Apply DC+ or AC hot to pin 4 for 1/2 second minimum while power (pins 1 & 2) is applied for 5 seconds minimum. The reset voltage must be at the same level as the voltage used to power the unit.

703 Counter (AC/DC or DC Only)To Display: Apply DC+ or AC hot to pin 1 and DC – or AC neutral to pin 2. The display is activated at this point but the count will not be started until a signal is applied to pin 3. Note, for proper operation: Power must be applied to pins 1 & 2 before or coincident with pin 3.

To Operate: Apply DC+ or AC hot to pin 3. The count is incremented when the input signal is removed from pin 3.

17

703 Counter continued The input signal must be applied for 1/2 second minimum (AC/DC model) or for 1 millisecond mimimum (DC Only model). If power (pins 1 & 2) has been applied for 5 seconds minimum, the incremented count will be stored in non-volatile memory when power is removed.

To Reset: (for Resettable Models) Apply DC+ or AC hot to pin 4 for 1/2 second minimum while power (pins 1 & 2) is applied for 5 seconds minimum. The reset voltage must be at the same level as the voltage used to power the unit.

732 Hour Meter (DC Only)To Activate Display: Apply DC+ to pin 1 and DC- to pin 2.

To Activate LED: Apply DC+ (for active-high models) or DC- (for active-low models) to pin 3 during indicator-on condition.

To Activate Elapsed Time: For models without separate enable option - elapsed time is activated when power is applied to pins 1 & 2. For models with enable option - apply signal to pin 4. Note: Power (to pins 1 & 2) must be applied before or at the same time as signal to pin 4.

18

732 Hour Meter continued Operation: Apply DC+ to pin 4 for 1 millisecond minimum. Activation (accumulation) of elapsed time is indicated by the hourglass icon flashing. Time accumulated will be stored into non-volatile memory when power is removed, if power (to pins 1 & 2) has been applied for the minimum of 5 seconds.

Reset: (for resettable models), Apply DC+ to pin 4 for 1/2 second minimum, while power to pins 1 & 2 has been applied for 5 seconds minimum. Note: The reset voltage must be at the same level as the voltage used to power the unit.

5. TROUBLESHOOTINGTo maximize the life of this meter, please read all instructions carefully and review Safety Precautions on inside front cover of this manual. Most minor problems can be resolved by removing all power for at least 10 seconds and then reconnecting.

Problem Possible CauseNo Display Power not connected or too low.

Display Present, but counter does not activate.

Input (or enable) wire not connected. Start Input not connected. Input voltage not reaching specified minimum signal level.

LED not turning ON during activation condition.

Switch or switch-connection faulty.
